    I have a 2004 2500 HD and I'm putting on a MM2 plow. Which color wires do I splice into for the parking lamps and turn signals. :confused:

    Thanks,

    No splicing necessary. Get the pig tales and plug then in.

    Turn Signal = purple wire
    Park = Brown
    DRL = Pink
    Use a test light to define the 12v+ from the turn/park bulb plug on the truck side, be sure to connect to the positive voltage side of the DRL. If you have any trouble with headlights functioning properly on the plow, don't be surprised if you have to reverse the wire polarity in ALL of the factory plugs which connect to the isolation module harnesses. Had to do this with my 04'

    Are you talking about the wires on the plow harness or the truck? Because the color wire on the truck side are Brown Blue & Black. Blue is turn signal, Brown is parking light, Black is ground
